The controlled function field, the function of control command in the characterization data bag, this function are the function that television terminal can provide, and like signal source switching, channel switching etc., account for 3 bytes.
Read/write field, the control command in the characterization data bag is read operation or write operation, accounts for 1 byte.
The new value that controlling value field, characterization control function are set up in control procedure accounts for 16 bytes.The mode of high-order alignment, low level polishing is adopted in the filling of controlling value field, and promptly when 16 bytes of controlling value less than, data begin to fill in from high order end, and low order end mends 0.For example, controlling value is 33, accounts for 2 bytes, and high 2 write 33 during filling, and low 14 write 0, and the result is 3300000000000000.
The controlling value type field, the data type of characterization control value accounts for 1 byte.The type of controlling value can include unsigned int unsigned int, three types of symbol integer signed int and character string char etc. are arranged; Three kinds of data types are expressed as to enumerate mode: 1 expression unsigned int; 2 expressions have the symbol integer, 3 expression character strings.
The controlling value length field, the length of characterization control value also is the shared effective word joint number of controlling value.Need not the control command of controlling value for having only controlled function, controlling value length is 0.For example, in the control command of " brightness regulation to 50 ", controlling value is 50, accounts for two bytes, and then controlling value length is 2; The control command that " signal source is switched to HDMI " need not controlling value, and so, the length of controlling value is 0.
The operating result field characterizes operation result information.Can adopt 0,1 to represent, if 1, expression is operated successfully, if 0, the expression operation failure.
According to above-mentioned communication protocol, to television terminal, then control end will be packed control command according to above-mentioned communications protocol format as if the control end transmitting control commands; To order bag to transfer to television terminal through communication interface then; At this moment, the operating result field is empty, is in disarmed state; Then; Television terminal will be according to same communications protocol format; After the operating result field write corresponding operation result information, through communication interface the response command packet is sent to control end again, then control end promptly know television terminal whether successful execution this control command.If control end need obtain the work at present state information of television terminal, the resource information of perhaps obtaining television terminal and being had then can only be filled a function digital section and controlled function field, is sent to television terminal through communication interface then; Television terminal is according to the description of controlled function field; Extract work at present state information or other resource informations and be filled to the controlling value field; And after corresponding filling controlling value type, controlling value length field and the operating result field, through communication interface the response command packet is sent to control end again and gets final product.
In data transmission procedure, if need once send a plurality of packets, can adopt the seamless link mode that separator is not set to transmit between packet and the packet between control end and the television terminal, to improve data transmission efficiency.
S25: flow process finishes.
When adopting said method to realize the two-way control of television terminal, can not influence the application of the unidirectional control mode that the original remote controller of television terminal controls.
Television terminal is as an important element of entertainment in the present family; Along with the Internet of Things and the arrival in Smart Home epoch, the unidirectional control mode of Traditional use IR remote controller control television terminal makes TV not merge with intelligent domestic system is perfect, can not meet consumers' demand; And the present invention has solved this problem well; Adopt the communication of simple two-way serial communication and network service etc. to connect, and cooperate the communication protocol of setting, thereby realized the two-way control of television terminal.
